You can find this place spelled in a lot of different ways: Mamean, Maumean, Mam Ean, Maum Ean, but you will not find lot's of information in the net on it.
Maumean is sometimes referred to as St Patrick's Well or Patrick's Bed and is located on a height of 320m. Mam Ean means Pass of the Birds.
This short (4km/2 1/2-mile) return walk follows the Great Western Way Walk to the top of a mountain pass which has long been associated with St. Patrick. This mountain walk goes along an ancient Pilgrim's Path to St. Patrick's second holy mountain (This is the only referral that I found). It is now the site of a small chapel, a hollow in the rock known as Patrick's Bed, a life-size statue of the saint, and a series of stone crosses, marking the 14 Stations of the Cross. You will have an excellent view over the surrounding area from this place.
To get there, you have to drive towards Lough Inagh, that is nestled between the Maumturk and The Twelve Ben Mountains in the heart of Connemara.
The mountain rises steep from the valley floor, and there are many small streams that fall into the lake. This you see if you follow the R344, that cuts through the valley, linking Recess to the south and Kylemore Lake to the north.
To reach the beginning of the walk, drive on the R344, turning right (if riding North) or left (if riding south) onto a side road. There is a sign for Maum Ean and a parking lot (don't use this one). Continue on this small side road for about 7 km to a large parking lot on the left. Park your car here, and follow the well-worn trail 4km return towards the top of the pass.
